A carbon steel dished head,also named torispherical head or flanged and dished(F&D)head,is a widely used pressure vessel end closure made of high-quality carbon steel material.It consists of a spherical crown,transitional knuckle radius and straight welding flange.With mature stamping forming technology,it features reasonable stress distribution,good structural rigidity and outstanding cost performance.
Carbon steel material provides excellent overall mechanical strength,weldability and pressure-bearing performance for the head.It can adapt to normal temperature,medium pressure working conditions and non-corrosive industrial medium.Thanks to simple manufacturing process and moderate cost,carbon steel dished heads are the most commonly selected closure parts for conventional industrial tanks and vessels.
